Ok, maybe the osc. coil is defective, but why does it test good and why do I have good grid voltage at all frequencies? I just noticed one other thing. While I have great volume, over the dial, I find that it is slightly difficult to tune in a strong station because the tuning is broad. I can turn the dial through about a 30 Khz range on strong stations. I suspect that the oscillator is working correctly, however maybe not at the correct frequency, because the average super has about -5 to -25 volts on the osc grid. On mine the grid, using a VTVM reads between -21 to -25V throughout the tuning range. Yes, a scope or frequency counter would help, but those I no longer own. The oscillator is definitely working. Correct frequency???
